Benefits of technology

This patent describes a liquid pharmaceutical formulation of an antibody that can be used to treat detrimental hTNFα activity. The formulation has a shelf life of at least 18 months and is stable even after being frozen and thawed multiple times. The antibody is directed against TNFα and is easily administered through injection. The formulation contains a high concentration of the antibody and is not light sensitive. The patent also provides data on the dissociation of the antibody from human TNFα and its ability to neutralize its cytotoxicity. Overall, this patent provides a solution for developing a stable and effective pharmaceutical formulation of an antibody for therapeutic use.

Problems solved by technology

While these mouse anti-hTNFα antibodies often displayed high affinity for hTNFα (e.g., Kd≦10−9M) and were able to neutralize hTNFα activity, their use in vivo may be limited by problems associated with administration of mouse antibodies to humans, such as short serum half life, an inability to trigger certain human effector functions and elicitation of an unwanted immune response against the mouse antibody in a human (the “human anti-mouse antibody” (HAMA) reaction).
However, because these chimeric and humanized antibodies still retain some murine sequences, they still may elicit an unwanted immune reaction, the human anti-chimeric antibody (HACA) reaction, especially when administered for prolonged periods, e.g., for chronic indications, such as rheumatoid arthritis (see e.g., Elliott, M. J., et al.
However, these hybridoma-derived monoclonal autoantibodies were reported to have an affinity for hTNFα that was too low to calculate by conventional methods, were unable to bind soluble hTNFα and were unable to neutralize hTNFα-induced cytotoxicity (see Boyle, et al.
However, because of their relatively fast dissociation kinetics, these antibodies may not be suitable for therapeutic use.

Preparation of the Formulation

[0112]The pharmaceutical formulation of the invention was made according to the following protocol.

[0113]Materials which were used in the formulation include: mannitol, citric acid monohydrate (citric acid), sodium citrate, disodium phosphate dihydrate (dibasic sodium phosphate dihydrate), sodium dihydrogen phosphate dihydrate (monobasic sodium phosphate dihydrate), sodium chloride, polysorbate 80, water for the injections, sodium hydroxide, which was used as a 1M solution to adjust the pH, and protein concentrate (e.g., antibody concentrate).

Preparation of 20 L of Buffer (Equivalent to 20.180 kg−Density of the Solution: 1.009 g / ml)

[0114]Ingredients were weighed out as follows: 240.0 g mannitol, 26.1 g citric acid monohydrate, 6.1 g sodium citrate, 30.6 g disodium phosphate dihydrate, 17.2 g sodium dihydrogen phosphate dihydrate, 123.3 g sodium chloride, 20.0 g polysorbate 80, and 19,715.7 to 19,716.1 g of water.

[0115]A sodium hydroxide solution was pre...

Freeze / Thaw Studies

[0121]After the formulation buffer for the D2E7 antibody was selected the drug substance was formulated in the same matrix as the finished product.

[0122]Freeze thaw behavior of the D2E7 antibody drug substance at a protein concentration of 63 mg / mL was evaluated by cycling drug substance 3 times from the frozen state to the liquid state. Table N shows the results of an experiment evaluating the effect of three fast and slow freeze-thaw cycles in the presence and absence of 0.1% polysorbate 80 starting from −80° C. or −30° C., respectively.

[0123]Table 2 shows that the D2E7 antibody drug substance can be thawed / frozen at least 3 times without any detrimental effect on either chemical (cation exchange HPLC, size exclusion HPLC, colour, pH), physicochemical properties (subvisible particles, clarity) or biological activity (in vitro TNF neutralization assay). Also table 2 shows that 5 the inclusion of polysorbate 80 improved the physicochemical properties of the D2E7 a...

Microbial Studies

[0125]Tests were performed to determine if the formulation can support microbial growth. The results from these experiments showed that the formulation does not support microbial growth if stored at 20 to 25° C. for 14 days. This result was determined by directly inoculating the sterile formulation with microorganisms (e.g., Staphylococous aureus, ATCC-No.: 6538P, Candida albicans, ATCC-No.: 10231, Aspergillus niger, ATCCC-No.: 16404, Pseudomonas aeruginosa, ATCC-No.: 9027, an environmental isolate) at low level (NMT 100 cfu / mL). Inoculated formulations were then examined for overall microbial growth, e.g., for changes in turbidity. A lack of turbidity was an indication of no overall growth, and was detected in the inoculated containers after 14 days. Further, no organisms could be reisolated from these containers. Thus it was concluded that the formulation does not support microbial growth under these conditions.

(1985) Science 230:630-632). Subsequently, a factor termed cachectin, associated with cachexia, was shown to be the same molecule as TNFα. TNFα has ...
